REDUCING EXPOSURE: Lead contamination in the air, in dust, and on your skin is invisible. Keep children and pregnant women away during use and until cleanup is complete. Risk can be reduced - but not eliminated - with strong ventilation; washing hands immediately after use of these products before eating or smoking; and careful cleaning of surfaces and floors with disposable wipes, after lead dust has had a chance to settle. Use a lead specific cleaner with EDTA, or hand soaps specifically designed to remove heavy metals.

WARNING: Melting lead and casting lead objects will expose you and others in the area to lead, which is known to cause birth defects, other reproductive harm and cancer. USE STRONG VENTILATION!

I can only attest to its accuracy since Ive never hunted with it, but at 100 yards it gives me sub-2inch groups consistently from two different rifled barrels! Im using Winchester hulls, primers and wads with a fold crimp on a Lee Load-All. From a Mossberg 500 with either their rifle sight or cantilevered scope mount barrels and cast from wheel weights or linotype, its an excellent performer!!!!!

Review Excerpt -Not mine

The Lyman load Im using is their 525gr. sabot slug loaded in the Federal field hulls with the white wad over xx.x grs. of Herco, and CCI209 primers.
I use approx. xx lbs. of wad pressure when seating them, load the slug in by hand, and then perform the regular fold crimp.
Ive shot them in 2 separate Remington 11-87s, and one Benelli semi auto all rifled barrels, and they shot phenomenally. I did a side by side comparison to the Hasting slugs and they outshot them by a wide margin.
The Benelli liked them so much that they shot cloverleafs at 75yds., and would probably do the same at 100yds., except for the wind that day.
The only doe my partner shot this last year the Benelli owner was a frontal shot at a slight quartering angle. The slug hit her in the chest and exited just in front of her offside flank. It knocked her back on her rump into a seating position and she was able to regain her footing and run off about 60yds. before dropping.
I gotta say, after almost 20 yrs. of dabbling with casting and loading shotgun slugs, these Lyman slugs are a delight.

Old Data but relevant

I had this same exact mold 20 years ago and loaded up some slugs for my shotguns in Win AA hulls with a the standard star crimper on my Mec 12 gauge loader. Going through my parallel choke Browning BPS accuracy was so-so, but when I put it in my rifled Win 1300 I was able to get softball sized groups at 165 yards. yes I like to test long range However an occasional flyer would open up the group substantially. Keep in mind, the newer slugs, ie Remington Copper Solid, Win Partition Gold, Fed Barnes Expander, would do that too in the fourth shot out of a group, but those issues were from rapid barrel heat. Those latter offerings would really heat my barrel up fast and accuracy would go literally off a cliff. My accuracy problems with the LYMAN slug I would most likely attribute to crimping as getting a consistent star crimp was a bit of a problem with my setup. The use of a fold crimp tool would likely improve upon the performance I experienced. Even so, it had enough promise that I am seriously considering revisiting my experiment with the above said crimping tool
